Part 5: PCB Fabrication: Gerber Files & Ordering PCB
Continuing Education Center 
9/28/2012  217 comments
Today is the clincher, to take our layout and generate manufacturing files commonly called Gerber files as well as the Bill of Materials (BOM). Then we'll use a Gerber viewer to review the files. We'll then go over the process of how to specify and get a quote from a PCB manufacturer.
Part 4: Finishing the Layout: Finishing Touches & Design Rule Check
Continuing Education Center 
9/27/2012  207 comments
To finish the layout, we'll need to add some vias for soldering on the wires. We'll also add some text to the board and fill in some extra copper to help with heat dissipation. Then we'll cover some power-supply-oriented design rules and show how to set up the program to do a Design Rule Check.
Part 3: Using PCB Layout Software: Custom Component Libraries
Continuing Education Center 
9/26/2012  317 comments
If we need a component that is not in the provided libraries and not found in online user groups, we can always create our own components. We'll go through a few examples and use as much copy-and-paste as possible to create custom symbols and footprints for our custom components. We'll also cover the common footprint design guidelines, such as pad size and spacing tolerance, and using Eagle layout designer to create custom library components to fit our needs.
Part 2: Using PCB Layout Software: Schematic Capture & Component Libraries
Continuing Education Center 
9/25/2012  238 comments
This second class will start with an overview of circuit board layout software. Continuing on with our LED driver, we'll be using freeware to capture the schematic of our design using built-in library components. Then we'll see the real power of the software as the captured circuit is translated into PCB footprints. This allows us to lay down copper traces on the board.
Part 1: Driver Design & Component Selection
Continuing Education Center 
9/24/2012  351 comments
We start off this series with an overview of the prototyping process from a circuit design to schematic capture to circuit board layout. We'll be using the example of the LED driver design using the HV9910 that we discussed in "Advanced LEDs & Displays" in May. In this first class, we'll start with a quick review of the circuit, then go over the Bill of Materials and start the component selection process using the DigiKey Website.
Part V: Networked Lighting in Support of Intelligent, Green Buildings
Continuing Education Center 
5/11/2012  332 comments
This session will cover the overall topology and controls of Intelligent Buildings and also discuss how networked LED systems fit into the picture.
Part IV: Understanding Cutting-Edge Displays (AMOEDs, OLEDs & LCDs)
Continuing Education Center 
5/10/2012  245 comments
This class will provide a survey of emerging display technologies related to LEDs and their respective market segments.
